  • Two new species belonging to genus Mycale are described from the waters around Geojedo Island and Gageodo Island, Korea. Mycale (M.) geojensis n. sp. seems close to M. (M.) adhaerens parvasigma Hoshino, 1981, but our new species has three categories of anisochelae. M. (Aegogropila) hentscheli n. sp. is closest to M. (A.) obscura (Carter, 1882) in shape and spicule, but has no large sigma.

  • 2000년 7월부터 2005년 5월까지 울릉도와 추자도에서 SCUBA 다이빙으로 채집된 해면동물을 동정$\cdot$분류한 결과 깃해면속(Mycale)의 2종 죽도깃해면[Mycale (Aegogropila) jukdoensis n. sp.]과 추자깃해면[Mycale (Mycale) chujaensis n. sp.)이 신종으로 밝혀졌다. 죽도깃해면은 M. grandis와 골편의 구성에서는 유사하지만 시그마체와 라피드가 M. grandis의 것보다 크고, 두 종류의 준아령침상체를 가진다. 또한 죽도깃해면의 이조상체 I은 M. grandis의 것보다 작다. 추자깃해면은 M. sulgata와 성장형태와 미소골편의 크기가 매우 유사하지만, 추자깃해면은 두 종류의 준아령침상체를 갖는 대신 M. sulgata는 단지 한 종류를 갖는다.

  • A study on marine sponges was conducted by SCUBA diving at Ulleungdo Island, Korea, from July 2001 to August 2003. Two species, Mycale (Naviculina) ulleugensis and Mycale (N.) neunggulensis, are new to science. Mycale (N.) ulleugensis n. sp. seems close to M. chungae based on the shape of spicules, but differs in the size of megascleres and sigmas, Mycale (N.) neunggulensis n. sp. seems close to M. flagellifer Vacelet and Vasseur in the type and size of spicules, but differs in the shape of naviculichela. Naviculichela I of M. flagellifer has a spine on the upper part of the felix.

  • A new marine sponges, Mycale (Carmia) ieoensis n. sp., of the family Mycalidae was collected SCUBA diving in June 2017 from Ieodo Ocean Research Station, Korea. M. (C.) ieoensis n. sp. is encrusting to irregular massive type, yellow in life. This new species is similar to M. nullarosette Hoshino, 1981 in color and growth form but it differs in spicule size and sigma shape. Spicule size of M. (C.) ieoensis n. sp. smaller than that M. nullarosette. Also, M. (C.) ieoensis n. sp. has two size toxa, but M. nullarosette is not. The new species are compared to other Mycale species from the Korean region, and similar species from elsewhere.

  • Bioassay-guided fractionation of $CHCl_{3}$ extract from the fermentation broth of a sponge Mycale plumose-derived actinomycete Saccharopolyspora sp. nov., led to the isolation of two known prodigiosin analogs - metacycloprodigiosin (1) and undecylprodigiosin (2). These compounds exhibited significant cytotoxic activities against five cancer cell lines: P388, HL60, A-549, BEL­7402, and SPCA4. This is the first report on the significant cytotoxicity of metacycloprodigiosin (1) against human cancer cell lines.

  • Several marine toxins with macrolide structure have been found to act on actin. One of these toxins is mycalolide B isolated from the genus Mycale. This compound belongs to macrolide antibiotics and consists of tris-oxazole with strong cytotoxic activity ($IC_{50}$: 10-50 nM for growth of L1210 murine leukemia cells). This compound was found to be an actin-depolymerizing agent with the mode of action distinct from that of the known actin inhibitor, cytochalasin D. Tolytoxin, a macrolide isolated from cyano-bacteria with similar chemical structure to mycalolide B, seems to have similar effect. Another macrolide compound, aplyronine A, showed the effects similar to those of mycalolide B. Although bistheonellide A, a dimeric macrolide, did not show a severing effect, it de polymerized F-actin and sequestered G-actin by forming 1 : 2 complex with G-actins. Swinholide A has a structure and effects similar to those of bistheonel-lide A. In conclusion, mycalolide B, tolytoxin, aplyronine A, bistheonellide A and swinholide A are the members of "actin de polymerizing macrolide" the mechanism of which is different from that of cytochalasin D.halasin D.
